WaterWetter helps reduce coolant temperatures when they try to rise above the ideal as well as providing rust and corrosion protection. Antifreeze doesn’t transfer heat near as well as water, soluble oils tend to coat the cooling system further impeding heat transfer. In a Model A cooling system...
